Specification of Letters Patent.

Application filed November 29, 1907. Serial No. 404,415.

To all whom it may concern:

Be it known that I, ALFREn BRILE, a citizen of the United States,residing at Encampment, in the county of Carbon and State of Wyoming,have invented certain new and useful Improvements in Miners Lamps, ofwhich the following is a specification, reference being had to theaccompanying drawings.

My invention relates to improvements in miners lamps and its object isto provide one which will be simple, strong7 durable and inexpensive inconstruction and exceedingly convenient to handle.

With the above and other objects in view, the invention consists of thenovel features of construction and the combination and arrangement ofarts hereinafter described and claimed, and lustrated in theaccompanying drawings, in which Y Figure 1 is a front view of myimproved miners lamp; Fig. 2 is a vertical longitudinal section; Fig. 3is a detail horizontal or transverse section taken on the planeindicated by the line 3-3 in Fig. 2; Fi 4 is aside eleva tion of thefeed or wick cy inder; and Fig. 5

is a perspective view of the support or holder for the lamp.

The invention comprises a cylindrical tubular body l-having open endsand a partition 2 arranged a suitable distance from its lower end andadapted to divide it into upper and lower chambers 3, 4. The upper one 3is adapted to receive the grease, ta low, oil, candle or the like thatis to be burned by the lamp and serves as a supply reservoir. Suchmaterial is introduced into the chamber or reservoir 3 through its opentop which is adapted to be closed by a Aremovable cap 5 having acentrally'arranged vent hole 6 and a surrounding flange whichfrictionally engages the upper edge of the body 1 and retains the capthereon. To prevent the latter from becoming lost I preferably attach itby a chain or the like 7.

The tallow or other material in the supply reservoir 3 is fed through avalve opening 8 arranged centrally in the partition 2 into the lowerchamber 4 into which latter telescopes a feed cylinder or cup 9. Thelatter has an enlarged or reinforced bottom 10 from the center of whichrises a tube 11 having a threaded upper end 12 to screw intoa tube 13which 1s formed integral with and depends from the partition 2 and atthe top of which is located the valve opening or seat 8.

In the tube 13 are formed outlet openings 14 which permit the tallow oroil passing through the opening 8 and into the tube 13 to pass throu hthe latter into the feed chamber or cylin er formed by the telescopingparts 1, 9. The-valve seat 8 which is preferably cone-sha ed is adaptedto receive a simif has at its lower extremity a notch to receive a screwdriver or similar tool by means of which the valve 15 may be adjustedtoward or from its seat 8 to control the feed of the tallow from thesupply reservoir to the feed chamber or reservoir. The edge of thebottom or head 10 of the feed cylinder 9 is preferably milled as shownso that it may be readily rotated to apply it or remove it from vthebody 1.

Projecting laterally from the cylinder 9 adjacent to its bottom is aburner tube 20 Which has an upwardly turned outer end and which isadapted to contain a wick 21.

-Formed upon the bottom 10 of said cylinder 1s a cup or pan 22 whichserves both to catch the drippings from the burner or wick tube and alsoas a starting cup, a wick 23 heilig adapted to be saturated in oil orgrease and placed in said cup or pan and ignited when it i's'desired tostart the lamp as presently ex lained.

n order to. enable the lamp to be readily suspended from any kind of asupport and adjusted so that its flame may be turned in any directionand disposed at different elevations7 I provide a holder 24 constructedof heavy wire and preferably from a single piece as shown. This holdercomprises a cylindrical coil 25 adapted to slidably receive the body 1and to frictionally engage it so that it will remain in any adjustedposition in the coil to support the lamp at the desired height orelevation. One end of the wire from which the holder is made is shapedto provide as ur 26 which may be readily forced into a wal orotherjvertical support, and its other end is bent upwardly from the coiland then curved outwardly and downwardly to provide a suspending hook 27which may be conveniently caught over or forced into a suitable support.A portion of the wire from which said support is made is shaped toprovide a handle 28 which preferably projects radially from the coil andin a direction opposite to that of the spur 26, the hook 27 beingdisposed preferably in a plane at right angles to that of the spur 26and handle 2S as clearly shown in Fig. 1.

In using the lamp it will be understood that it is designed to burngrease, tallow oil or any other illuminating material or substance thatwill harden when cold and that will liquefy when heated. Such materialis placed in the supply chamber or reservoir 3 through its open topafter the cap 5 is removed. When it is desired to start the lamp thewick 23' is ignited and allowed to burn and heat the burner tube 2() andthe adjacent parts of the lamp so that the illuminating material in thefeed cylinder will pass through the wick 21 and burn at the upper end ofthe tube 20. The heat from this iiame gradually warms the entire body ofthe lam and liqueiies the material in the same so tiat it feeds from thechamber 3 down through the valve opening 8, the tube 13 and theapertures 14 into the feed chamber or cylinder. By adjusting the valvestem 16 the feed of the illuminating material may be regulated as jdesired. The holder 24 provides an eXceedingly convenient means forcarrying or suspending the lamp and owing to its slidable and rotatableengagement with the body, the latter may have its flame turned in anydirection and adjusted at different elevations. When the flame of theburner is eX- tinguished the illuminating substance will harden andcease to feed through the valve opening 8.

From the foregoing it will be seen that my lamp willbe exceedinglyeconomical in operation since there will be practically no dropping ofthe grease, as is the case when candles are used. The tallow or oil iscompletely consumed and by burning it as set forth a better light isobtained than that given by the ordinary candle. It is easy to light andextinguish and there is no waste or dropping of grease whenit isextinguished. It will be further noted that the device is simple, strongand durable in construction and that it may be produced at acomparatively small cost.

Having thus described my invention what I claim is:

1. A miner/s lamp comprising a body havin@ a horizontal partition formedwith a vailve seat and adapted to divide it into an upper supplychamberand a lower feed or wick chamber, said partition being formed upon itsbottom with a depending tube which surrounds the valve seat and formedwith transverse apertures, a feed cylinder to telescope the lowerchamber and provided upon its bottom with a central tube having a screwthreaded engagement with the, depending tube upon the partition, a screwthreaded valve stem arranged in the last mentioned tube and having avalve at its upper end to engage said seat and a wick tube projectinglaterally from the lower portion of the feed cylinder.

2. A miners lamp comprising` a body havin a horizontal partition. formedwith a va ve seat and adapted to divide it into an upper supply chamberand a lower feed or wick chamber, said partition being formed upon itsbottom with a depending tube which surrounds the valve seat and isformed with transverse apertures, a feed cylinder to telescope the lowerchamber and provided upon its bottom with a central tube having a screwthreaded engagement with the depending tube upon the partition, a screwthresnled valve stem arranged in the last mentionml tube and having avalve at its upper end to engage said seat, a wick tube projectinglaterally from the lower portion of the feed cylinder, a starting cup orpan upon the feed cylinder beneath said wick tube and a removableclosure for the upper end of the body.

In testimony whereof l hereunto affix my signature in the presence oftwo witnesses.
